QHeaderView - no big update work if updates are disabled
This is not a major boost, but still a nice optimization
that can speed up hideSection and resizeSection with about 40%
if updates are disabled.
It is backport of SHA 3bb0c88de8894fc05ad1558b96ae05ceeff64b78
and a5201007f255a07f7ba07981745eeaec41a14a34
